I think you are being unduly critical, if not arguably unrealistic in your expectation of the product?

Positive aspects of mass left aside in the debate, I don't think that anyone would argure that lighter isn't desirable in terms of either wing loading or sustained vertical performance, but;

At 3.8kg (8½lb) CMPro's Swallow EX allegedly intended for a 90 weighs-in at more than your suggested target maximum for a 110, as does The World Models Mfg. Zen 90 at 3.8kg (8½lb), both incidentally, of lesser wing area than CMPro's Leo 110. The Leo is a mass produced viably priced ARF, not a lovingly hand selected material and painstakingly craftsman built unit over which every gram has been eradicated with angst at great expense in time, money and labour so it might properly display the prowess of a world champion class flyer rather than those of the hoi polloi competitor akin to our humble selves for whom it is intended.

I personally think that seeking of status guised as 'pursuit of perfection' based predominently upon how big your wallet is, is where pattern per se has lost the plot in terms of appeal to the R/C masses, becoming ever more entrapped in a noose of the wannabe clique elite's making.
